That's really what it is. If we didn't use intrinsics for BLENDVPS/BLENDVPD/PBLENDVB all the way to isel, this is the node we would use.

The Android sanitizer tests are currently some of the most difficult
to run correctly, requiring at least 3 build directories which have
to be configured in just the right way and built in the correct order
(see e.g. [1] and the functions that it calls).
This patch adds a check-hwasan target which greatly simplifies running
the hwasan tests for gn users, taking advantage of its support for
multiple toolchains. With this the tests can be run simply by setting
an NDK path and running "ninja check-hwasan" with a compatible Android
device connected. The Linux/x86_64 and Android/aarch64 targets are
tested in parallel.

This really is only implemented on Windows, and it requires us to pull
in User32. This was only useful when debugging on lldb-mi on Windows, and there
doesn't seem to be a good reason why using a dialog box is better than what
exists for other platforms.

We're trying to have the vXi1 types in IR as much as possible. This prevents the need for bitcasts when the producer of the mask was already a vXi1 value like an icmp. The bitcasts can be subject to code motion and interfere with basic block at a time isel in bad ways.

Summary:
We have seen performance regression when v_add3 is generated. The major reason is that the v_mad pattern
is broken when v_add3 is generated. We also see the register pressure increased. While we could not properly
estimate register pressure during instruction selection, we can give mad a higher priority.
In this work, we raise the priority for mad24 in selection and resolve the performance regression.

Looks like the sanitizer-x86_64-linux-android bot started failing

This is necessary so that all of the part which is local to the

When generating a reproducer in LLDB we build up the mapping but don't
immediately copy over the files on the file system.
Rather than keeping a separate data structure with real and virtual
paths, we might as well reuse the entries already stored in the
YAMLVFSWriter to lazily copy over the files when needed.

Summary:
The documentation for this clang-checker did not explain what the options are. But this checkers only works with at least some options defined.
To discover the options, you have to read the source code. This shouldn't be necessary for users who just have access to the clang-tidy binary.
This revision, explains the options and gives an example.

Add a ANDROID_SERIAL_FOR_TESTING CMake variable. This lets you
run the tests with multiple devices attached without having to set
ANDROID_SERIAL.
Add a mechanism for pushing files to the device. Currently most
sanitizers require llvm-symbolizer and the sanitizer runtime to
be pushed to the device. This lets the sanitizer make this happen
automatically before running the tests by specifying the paths in
the lit.site.cfg file.

The path to the resource directory will end up being used in several
more places once the support for running check-hwasan lands. This
moves the definition to a central location so that it can be used
from those places.

Prepend -fuse-ld=gold instead of appending it so that the linker can

Implements PR40180.
clang-cl has one minor behavior difference with cl with this change.
Clang allows the user to enable the C++17 feature of aligned allocation
without enabling all of C++17, but MSVC will not call the aligned
allocation overloads unless -std:c++17 is passed. While our behavior is
technically incompatible, it would require making driver mode specific
changes to match MSVC precisely, and clang's behavior is useful because
it allows people to experiment with new C++17 features individually.
Therefore, I plan to leave it as is.

Summary:
When running llvm-objdump with the -macho option objdump will by default
disassemble only the __TEXT,__text section (or __TEXT_EXEC,__text when
disassembling MH_KEXT_BUNDLE files). The -disassemble-all option is
treated no diferently than -disassemble.
This change upates llvm-objdump's MachO parsing code to disassemble all
__text sections found in a file when -disassemble-all is specified. This
is useful for disassembling files with more than one __text section, or
when disassembling files whose __text section is not present in __TEXT.
I added a lit test case that verifies "llvm-objdump -m -d" and
"llvm-objdump -m -D" produce the expected results on a reference binary.
I also updated the CommandGuide documentation for llvm-objdump.rst and
verified it renders correctly as man and html.

In keeping with our general direction of having the vXi1 type present in IR, this patch converts the mask argument for avx512 gather to vXi1. This can avoid k-register to GPR to k-register transitions late in codegen.
I left the existing intrinsics behind because they have many out of tree users such as ISPC. They generate their own code and don't go through the autoupgrade path which only works for bitcode and ll parsing. Ideally we will get them to migrate to target independent intrinsics, but it might be easier for them to migrate to these new intrinsics.
I'll work on scatter and gatherpf/scatterpf next.
